Unsupported Architectures during upload to store

Hi

Context:
I have an app for ios and android developed with dotnet maui.
Normally during summer time the development stops and I pickup the development during the winter.
I am doing the development and builds on a M2 MacMini in VSCode.
I updated my Mac to 27 (GoldenGate). Running XCode 26.6 (and XCode 27). And the latest dotnet sdk and workload for maui.

I updated my project with the latest packages, did a minor code update and tried to use Transporter to upload to the Store for TestFlight.

The upload fails because it detects a unsupported architecture (x86_64) coming from the libskiasharp.framework in the IPA.

lipo indeed states that the ipa zip contains that architecture.

What is going wrong here, why is this now happening.

I am chasing my tail here.

Thanks

    My solution in the end is to add a section in my csproj which executes the removal of the framework during release build of ios.

        <Target Name="StripSkiaSimulatorSlice"
            Condition="$(TargetFramework.Contains('-ios')) and '$(Configuration)' == 'Release'">
        <Exec Command="xcrun lipo -info &quot;$(AppBundleDir)/Frameworks/libSkiaSharp.framework/libSkiaSharp&quot;" />
        <Exec Command="xcrun lipo -remove x86_64 &quot;$(AppBundleDir)/Frameworks/libSkiaSharp.framework/libSkiaSharp&quot; -output &quot;$(AppBundleDir)/Frameworks/libSkiaSharp.framework/libSkiaSharp&quot; || true" />
        <Exec Command="xcrun lipo -info &quot;$(AppBundleDir)/Frameworks/libSkiaSharp.framework/libSkiaSharp&quot;" />
    </Target>


        <PropertyGroup Condition="$(TargetFramework.Contains('-ios')) and '$(Configuration)' == 'Release'">
        <Platforms>arm64</Platforms>
        <RuntimeIdentifier>ios-arm64</RuntimeIdentifier>
        ...
        <ArchiveOnBuild>true</ArchiveOnBuild>
        <TcpPort>58181</TcpPort>
        <BuildIpa>true</BuildIpa>
        <CodesignDependsOn>$(CodesignDependsOn);StripSkiaSimulatorSlice</CodesignDependsOn>
    </PropertyGroup>
